Title: PBX with internal dialling - disables call pre-routing when calling subscriber is one to whom incoming calls are to be re-routed
Inventor: JAEGER HORST
IPC: H04Q3/62
Filed: 1980-02-28
Abstract: The telephone system compares the address of the wanted subscriber station with the address of the calling subscriber from the first network. This occurs when call re-routing occurs with the wanted subscriber station in the second network and after converting the address of the wanted subscriber station into a form appropriate for handling by the re-routing system. If the address of the wanted station is the same as the address of the calling subscriber then no call re-routing occurs but rather a connection is initiated.

Patent DE-3106250-A1 (DE)
Inventor: REIMERDES ERNST H DR
IPC: A23C19/06
Filed: 1981-02-20
Abstract: The invention relates to a process for producing aroma-containing food products in which exogenously and/or endogenously formed enzyme complexes are separated from specific pure or mixed cultures of microorganisms, which develop certain characteristic flavoring and aromatizing agents. The enzyme complexes are subsequently added to an aqueous solution or suspension of a substrate. The isolated enzyme complexes are optionally concentrated or standardized beforehand under careful conditions. The mixture of the substrate and enzyme complexes subsequently undergoes biochemical rapid ripening under suitable conditions until the desired aromatizing and flavoring agent concentration is obtained. The biochemical rapid ripening is then terminated by substantial inactivation of the enzyme complexes. The ferment solution or suspension obtained and which contains the desired flavoring and aromatizing substances, can be added to basic food substances for aromatizing them.

Title: Circuit arrangement for driving a rotary anode in an X-ray tube
Inventor: GLAESEL JOACHIM DIPL ING
IPC: H05G1/66
Filed: 1981-08-05
Abstract: The invention in this case relates to a circuit arrangement in the case of which stator windings (which are connected to an AC voltage source and consist of a main winding and an auxiliary winding) produce a rotating field (via a capacitor auxiliary phase) for driving the rotor which is coupled to the rotary anode. The aim and object are to create a circuit arrangement which, without any major additional cost, ensures (during operation of the X-ray tube for X-ray examination) that the rotary anode rotates at a speed which can be predetermined, is constant and is low in comparison with the method of operation of such X-ray tubes for X-ray photographs. This is achieved according to the invention in that a switching means is provided with whose aid (during the operation of the X-ray tube for X-ray examination) a rectifier element or (in the case of stator windings which have a plurality of parts in each case) possibly a rectifier bridge circuit is connected in the stator circuit in such a manner that a portion of the stator windings is subjected to a direct current in order to produce a stationary magnetic field which is superimposed on the rotating field. <IMAGE>

Title: Motor vehicle with four-wheel drive
Inventor: SCHMIDLER RUDOLF
IPC: B60K17/35
Filed: 1981-11-14
Abstract: The invention relates to a motor vehicle with four-wheel drive, in which the wheels of one axle are constantly driven by a drive source by way of a gearbox and a differential and the wheels of the second axle are automatically connected by way of a multi-plate clutch at a differential speed to the first axle, the outer plate carrier of the clutch being constantly driven and the inner plate carrier being connected to the axle which is not constantly driven. The multi-plate clutch is connected by simple and structurally advantageous means as a differential between the wheels of the second axle in that the outer plate carrier is the differential case of the differential and two inner plate carriers, rotatable independently of one another, are connected to the wheels. The multi-plate clutch is preferably a plate slip clutch interacting with fluid which in the event of a speed differential between the plates transmits torque by shearing action.

Patent DE-3204246-A1 (DE)
Title: Front wheel drive which can be switched on or off for a motor vehicle with a constant rear wheel drive, in which the engine and the gearbox are located at the front
Inventor: SCHMID LEOPOLD F
IPC: B60K17/34
Filed: 1982-02-08
Abstract: According to the prior art, front wheel drives of the abovementioned type are achieved by way of a rigid front axle which drives both front wheels. Rigid front axles have the disadvantage, however, of a large unsprung mass and a correspondingly poor ride comfort. Since they also raise the engine and gearbox block and hence the overall centre of gravity of the motor vehicle in a manner which is unacceptable for the drive characteristics of a modern passenger car, there have to date been no such front wheel drives in passenger cars but only in off-the-road vehicles and lorries. In order to avoid this disadvantage, the front wheel drive according to the invention is derived by means of a take-off transmission arranged on the rear end of the gearbox and the line of forces are then led by way of a drive shaft to a bevel gear transmission and from there to only one of the two front wheels. Since when driving with only one person and without luggage the one driven front wheel is loaded with approximately 30% of the total weight of the motor vehicle, the drive adhesion of the motor vehicle is increased by the considerable value of 75% by virtue of the drive of the one front wheel which does not need a differential and is therefore always fully effective.
